Answer:
Trichomoniasis
Explanation:
Trichomoniasis is an sexually transmitted disease that affects around 30% of world population. The common symptoms are frequent urge to urinate, vaginal bleeding, burning sensation during urination.
The causative agent of trichomoniasis is a protozoa called <em>Trichomonas vaginalis</em>. This protozoan can be transfer through the genital contact. The protozoa can easily be transfer from affected individual to the healthy individual.
Thus, the correct answer is option (3).
''The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears. It was once thought that Cambrian rocks contained the first and oldest fossil animals, but these are now found in the earlier Ediacaran (Vendian) strata.''
The correct answers are:
b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.
All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.
c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.
As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
